series introduction
# IS42S16160D - 6TLI Product Series Introduction
## 1. Overview
The IS42S16160D - 6TLI is a high - performance Static Random - Access Memory (SRAM) product series designed to meet the demanding requirements of various electronic applications. SRAM offers several advantages over other types of memory, such as faster access times and lower power consumption in certain scenarios, making it an ideal choice for applications where speed and efficiency are crucial.
## 2. Key Features
### 2.1 Memory Organization
- The IS42S16160D - 6TLI features a 16M - bit organization, specifically arranged as 1M words by 16 bits. This organization allows for efficient data storage and retrieval, enabling seamless integration into systems that require large - scale data handling. For example, in data acquisition systems, this memory capacity can store a significant amount of sensor data for subsequent processing.
### 2.2 Fast Access Time
- With an access time of 6 ns, this SRAM series provides extremely fast data access. In high - speed digital systems, such as networking equipment and high - performance computing platforms, the short access time ensures that data can be read and written quickly, reducing latency and improving overall system performance. For instance, in a network router, fast access to routing tables stored in the SRAM can significantly enhance packet forwarding speed.
### 2.3 Low Power Consumption
- The IS42S16160D - 6TLI is designed with power efficiency in mind. It consumes relatively low power during both active and standby modes. This is particularly beneficial for battery - powered devices, such as portable medical devices and handheld communication devices. Lower power consumption not only extends the battery life but also reduces heat generation, which can improve the reliability and stability of the device.
### 2.4 TTL - Compatible Inputs and Outputs
- The inputs and outputs of the IS42S16160D - 6TLI are TTL (Transistor - Transistor Logic) compatible. This means that it can be easily interfaced with other TTL - based digital circuits without the need for additional level - shifting circuitry. This simplifies the design process and reduces the overall cost and complexity of the system.
### 2.5 Industry - Standard Packaging
- The product is available in industry - standard packages, which ensures easy integration into existing printed circuit board (PCB) designs. The standard packaging also allows for compatibility with automated assembly equipment, facilitating mass production and reducing manufacturing costs.
## 3. Electrical Characteristics
### 3.1 Supply Voltage
- The IS42S16160D - 6TLI operates with a supply voltage of 3.3V ± 0.3V. This voltage range provides a balance between power consumption and performance, making it suitable for a wide range of applications. The relatively low supply voltage also contributes to the overall power efficiency of the device.
### 3.2 Input and Output Levels
- The input high voltage (VIH) is typically 2.0V, and the input low voltage (VIL) is typically 0.8V. The output high voltage (VOH) is typically 2.4V, and the output low voltage (VOL) is typically 0.4V. These voltage levels are well - defined and comply with industry standards, ensuring reliable communication between the SRAM and other components in the system.
### 3.3 Current Consumption
- During active operation, the device has a relatively low active current consumption, which helps to minimize power dissipation. In standby mode, the current consumption is even lower, further conserving power when the device is not actively being accessed.
